WINDOW LIQUID.

Ne Drawing.

This invention relates generally to window panes, and has moreparticular reference to a novel liquid for application to the windowpanes for preventing water or snow from clinging thereto.

The invention has for an object the pro-- vision of an improved windowliquid which will be elficient in action, and which can be manufacturedand sold'at a reasonable cost, and which contains nothing of aninjurious or deleterious nature.

lhe liquid applied to a window pane also prevents the formation of frostthereon.

F or further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following description,and to the appended claims in which the various novel features of theinvention are moreparticularly set forth.

In compounding the invention liquid, use

-is made of paraflinum liquidum (paraffin oil), Oregon balsam lir(kandabalsam), Xylene (xylol), toluene (toluol), melted celluloid, ethylacetate, acetone, and castor oil. The compound functions without the useof thecastor oil, but a streaky appearance in the final result ispresent, which appearance is made smooth and streakless by the use ofthe castor oil. It may be desirable to have the liquid coloured, and anysuitable paint may be used, such as fuchsin.

The invention liquid may be compounded, for example, by thoroughlymixing together 3 grams of paraffin oil, 1. gram of castor oil, 3 gramsof kandabalsam, 3 grams of toluol, 1 gram of melted celluloid, 1 ounceof ethyl acetate, and 1 ounce of acetone. Colouring may be added so asto obtain any desired shade.

The resulting liquid is suitably bottled and thus sold. The liquid maybe applied to either side of a window, or to both sides. Before applyingto a Window it is desirable to wash and dry the window thoroughly.Thereafter apply with a soft brush, using an up and down stroke. Toobtain the best results, for automobile windows, apply While the car isin a garage and the windows and doors of the garage are closed, so thatdust cannot deposit on the glass while applying the liquid. Afterapplying the liquid is left to dry forming like a skin over the window,which can be removed by scraping. The invention liquid is non-flammab sothere is no danger of fires.

Application filed October 21, 1926. Serial No. 143,299.

In providing a coating for gla'ss which will prevent the collection ofwater thereon it isessent'al to employ a substance which will betransparent when dry, which may be easily applied in a smooth thincoating and which will resist the formation of drops of water and thecollection of such drops of water on the surface of the glass. It hashas been found that melted celluloid together with kandabalsam providesa lac uerl'ake substance having the desired qua ities and well adaptedto be used on glass. It has been further found by experiment that asolvent resulting from mixtures of ethyl acetate, acetone, toluol, andXylene provides a most satisfactory solvent which is highly volatile,and thus renders the composition capable of drying rapidly. Thesepartied lar ingredients produce a transparent coating which flows freelyfrom a brush. The

presence of the oils in the composition causes the same to resist thecollection of water on the surface of the dried coating.

Since water vapor, snow, etc., cannot cling to a window treated with theinvention liquid, the windows remain transparent regardless of snows,rains, etc.

lVhile I have described my invention with some degree of particularity,I realize that in practice various alterations therein may be made. Itherefore reserve the right and privilege of changing the form of thedetails, or otherwise altering the arrangement of the correlated partswithout departing from the spirit or the scope of the appended claims.

Having thus described myinvention, what I claim as new and desire tosecure by United States Letters Patent is 1. A window liquid, forpreventing moisture, formation of frost, rain, or snow from engagin onwindows, comprising paraffin oil, kan dabalsam, 'xylol, toluol, meltedcelluloid, ethyl acetate, acetone, and colouring means.
